A hand held tool for installing a threaded fastener in which the tool is adapted for use solely as a drill bit, solely as a screwdriver, and as a combination thereof, wherein the threaded fastener has a central bore extending therethrough. Extension of the drill bit beyond the end of the screwdriver blade may be selectively controlled, and the drill bit may be maintained in its entirety within the shaft of the screwdriver when not in use to thereby preserve the sharpness of the drill bit. A unique locking collar is also provided.
